    <h1>Search the GVK (Common Union Catalogue)</h1>

    <p>The GVK search capability can be used to query the <a href="http://www.gbv.de/">GVK</a> (Common Union Catalogue) and automatically import references into JabRef.</p>

    <p>To use this feature, choose <b>Search -&gt; Web search</b>, and the search
    interface will appear in the side pane. Select <b>GVKFetcher</b> in the dropdown menu.</p>

    <p>You can simply enter words / names / years you want to search for, or you can specify search keys.</p>

    <p>Supported keywords are</p>
    <ul>
        <li>all - all words. Not specifing a search key results in an "all" search</li>
        <li>tit - title words</li>
        <li>per - authors, editors, etc.</li>
        <li>thm - topics</li>
        <li>slw - key words</li>
        <li>txt - tables of content</li>
        <li>num - numbers, e.g. ISBN</li>
        <li>kon - names of conferences</li>
        <li>ppn - Pica Production Numbers of the GVK</li>
        <li>bkl - Basisklassifikation-numbers</li>
        <li>erj - year of publication</li>
    </ul>

    <h3>Notes</h3>
    <ul>
        <li>queries can be combined with "and". The use of "and" is optional, though.</li>
        <li>in many cases you can use the truncation sign "?"</li>
        <li>spaces in person names are not supported - I am working on it. Please use the truncation sign ? after the first name for several given names. E.g. "per Maas,jan?"</li>
    </ul>

    <h3>Sample queries</h3>
    <ul>
        <li>"marx kapital"</li>
        <li>"per grodke and tit db2"</li>
        <li>"per Maas,jan?"</li>
    </ul>
